Ptvs: Refresh DB always fails on Visual Studio 2017 RC

[vitskr]

Refresh DB always fails on Visual Studio 2017 RC. It works just fine on same PC within Visual Studio 2015. I tried Anaconda3 both x64 and x86. Tried Python 2.7, Python 3.5 all bitness. But it always fails. Attached diagnostics info. Right now i have anaconda3 4.2.0 installed and set as default environment

Thanks everyone for the reports! It's great that you're all jumping on VS 2017 and passing on the feedback - we really appreciate it.

In this case, we found the bug just before release and weren't able to get a fix ready in time, but it's coming in the next update. Until then, I'm afraid there's no easy workaround (though if you're missing a particular library, what you _can_ do now is add a search path to your site-packages folder and we won't run out of memory anymore - as this is the feature that caused this bug, it's somewhat fitting that it's the best available workaround right now).

I'll leave this bug open for now to save people filing it again, but rest assured, there will be a fix soon.

Just for reference, this was also reported as #1784, #1793, #1878 and was fixed in #1797.

I have the same problem when I want to use Anaconda3 and code autocomplete does work well

The fix for this is in the latest update of VS 2017 RC. If you install it today (or in the last 2-3 weeks), you should have the fix. Otherwise, make sure you install the updates when it prompts you in VS.
